Document Summary
How organisms interact with their environment: ecology. Environments are changing more constantly than they have in the past 3. 5 billon years. Organismal ecology: morphological, physiological and behavioral adaptations, adaptations allow organisms to stay where they are currently living, salmon: 5 years feeding and growing in the ocean, migrate back to the stream they originally hatched from. Females lay eggs in the gravel, male will compete to fertilize the eggs. Conservation biology: study, perceive and restore threatened population, communities, ecosystems. Ecologist study: interactions between organisms and their environment results in a species being found at a certain area with a certain population size. Conservation biologist: apply these data to perceive species and restore environments. In fresh and salt water, 3 factors affect the distribution and abundance of organisms: nutrient availability, water depth and water movement. Spring and fall turnovers occur due to temperature change. Spring turnover: water and bottom of lake has nutrients that are brought to the top.
